Had a hose split last night. I was working on it, and it split between the two hose clamps. I want the best water hose I can get, as the run is very short <3' the diameter is 5/8". What is the best?

What will the line be doing ? I like Trident Blue hose .
Series 252 Corrugated Exhaust/Water Hose (with Wire) | West Marine
They have different types from just regular hose to Nuke proof .

generator water intake

 

[westsailpatti]

OK , for intake you need the hose with a spiral wire molded in .

When I just took the old one off, thats what it had, however rusted the wire was now.

The hose then went into a big basket strainer, may I change that to something like this?:

Because the intake is so close to the surface of the water, I need to save space before it goes into the march pump I am using for cooling, also below the water.

 

[westsailpatti]

If the wire was rusted and the hose split sounds like it was really old . Good luck . Are you sure it was Trident hose ?

 

[UnionPacific]

It was most likely as old as the ferrymann diesel generator. However the thru-hulls were all bonded, and in fantastic shape, they all work very good. The only one I need to replace is the one for the engine, because it is a gate valve, but still also works great.

I like Defender for almost anything (best service and prices) and Hamilton next. Our West Marine in Burlington is the choice of last resort. They only hire people who have never seen a boat and signed an affadavit ,lousy selection even on line, higher prices.Defender has speed of light return time which counts when you have split hoses... Duct tape only takes you so far.

For a foot of hose, I use the local west marine. Its $8 but I can get it now. If no west marine I use lowes or HD. I buy my pressure water line at HD and save a lot over west.

You may regret ditching the big strainer when you pull a jellies into that dinky thing. Even the standard tiny vegetative flotsom will clog that small screen in no time. Better to have a big honking strainer.

I looked around a bit more, and found this one.
SHURFLO Raw Water Strainers | West Marine
Any better in your opinion? Still small, but not overly so.

 

[daledog]

yeah. You want wire reinforced exhaust hose. It's a ***** to work with but I use it for all thru-hull water. Scuppers, intakes...

IMHO, the bigger the better, particularly for an expensive device that has no "run dry" capability like a diesel genset. It's a PITA, but just a PITA, to have to frequently clear a strainer feeding something like a diaphragm pump for a water cooled fridge compressor which doesn't draw that much water but that won't die if starved. A genset will draw a lot of water, increasing the PITA factor with a small strainer, with expensive repairs to follow if/when it can't get enough.

Regarding the strainer the reply from IStream should be emphasized, a "big honking strainer" is far better than what you are showing. You don't want the generator starved for cooling water with a small amount of seaweed,jellyfish etc. The strainers you show have fine mesh and little surface area, thus easily clogged. Do you have good temperature alarms on the generator to warn you of problems? The bowls on the Jabsco do not have many threads and can crack far easier than you may think (don't ask me how I know), below the water line I would not like this. You are wisely concerned over the correct hose, I would suggest not skimp on the strainer.

 

[VallelyJ]

Exhaust hose is about the best you'll get for the purpose, and for <3' of 5/8" cost shouldn't be much of a factor. It's what you want for any hose that's below waterline. You can get it with wire ('hardwall') or without ('softwall'). The wire is good if you have to make sharp bends as it prevents kinking. That's about all it does, and there's no real difference otherwise. And I seriously doubt that your generator water pump produces enough suction to collapse softwall exhaust hose. However, for a little extra money, if wire gives you more peace of mind, get it. As Westsailpatti said, Trident is a good name and readily available. For that small amount of hose, if there's a marine store near you that has 5/8", I'd just buy it there, though it's an odd size.
Sounds like your old hose was just too old. Or, maybe the hose clamps were too tight and cut the rubber.

going to order this:

[RobGallagher]

Ditto the others on the bigger strainer. That little thing is meant for your fresh water tanks.... and that cheap plastic screw on cover will break easily... just ask me, I'll tell you.

 

[UnionPacific]

Can I use a large strainer on its side?

 

[mitiempo]

Can I use a large strainer on its side?

No. They are designed to be mounted upright.

I agree with IStream and others. The first strainer is for a fresh water pump, and only that.

The best strainer is probable a Groco ARG. GROCO STRAINERS

Sherwood makes good strainers that are more affordable and similar to the 2nd you showed in different sizes and with fine or course mesh. Sherwood Pumps - Raw Water Strainers - Sherwood

I would use hardwall water hose for the intake.

 

[UnionPacific]

My issue is that space between the hull and waterline is about 6" in this spot.
A lot of people say use hard wall, and I will.
